Abstract

Prikazan je optički memorijski uredjaj, koji ima blok (11) za brisanje informacija, sa šemom pobudjivanja visokofrekventnog pražnjenja i elektrodama (12) i (13) izmedju kojih se nalazi optički nosač (10) informacija, tako da se visokofrekventno pražnjenje javlja u hermetički zatvorenoj šupljini (5) nosača (10) informacija.An optical memory device is shown, which has a block (11) for erasing information, with a high-frequency discharge excitation scheme and electrodes (12) and (13) between which there is an optical carrier (10) of information, so that the high-frequency discharge occurs in a hermetically sealed cavity (5) of the information carrier (10).
